For making the object, technical solutions and advantages of the present invention clearly understand, hereafter will be described in further detail technical solution of the present invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine arbitrarily mutually.
Embodiment 1
The present embodiment provides a kind of for the overload controlling method in the discovery procedure of D2D communication equipment, mainly comprises following operation:
In the discovery procedure of D2D communication equipment, when network side gets the indication information of device discovery resource overload, according to preset device discovery premature beats strategy be device discovery user redistribute device discovery resource or according to preset the service of device discovery premature beats Developing Tactics device discovery.
Wherein, the process of the indication information of network side acquisition device discovery resource overload is as follows:
During D2D communication equipment finds, receiving terminal UE measures and judgment device discovery load overload situations, and reports overload indication information to network side.
Particularly, the judgement of load overload situations, can according in device discovery procedure, and whether the ratio that receiving terminal UE measurement discovery service used resource accounts for whole resource pool meets or exceeds preset ratio value to judge.Namely the ratio measured meets or exceeds preset ratio value, then determine device discovery resource overload, needs the indication information finding resource overload to network side reporting equipment.Or receiving terminal UE records the detectable signal number of successfully decoding, if the sum of the detectable signal of the successful decoding of record exceedes predetermined threshold value, then determine device discovery resource overload, need the indication information finding resource overload to network side reporting equipment.
And the device discovery premature beats strategy preset can comprise as follows:
1. network side gives device discovery user resource allocation pond again.
2. reduce device discovery number of users.
3. reduce device discovery service number.
In real process, can be used alone also can be with the use of for above-mentioned three kinds of methods.
The implementation procedure of said method is described in detail below in conjunction with accompanying drawing and embody rule.
First, the implementation procedure of said method is described from network side, this process as shown in Figure 1, comprises the steps:
Step 101: network side eNB receives the indication information of the device discovery resource overload that UE sends.
Particularly, the indication information of described device discovery resource overload can be indicated by 1 bit information, such as 1 representative overload, and 0 represents nonoverload.
This indication information can be carry out drawing after load overload judges in UE side, and can be trigger-type to the mode of network side report, such as, when UE side judges that load is transshipped, can realize triggering reporting to network side; Also can be reporting of periodic.
And the process that the judgement of load overload is carried out in UE side is as follows:
In an example, in device discovery procedure, receiving terminal UE searches for the detectable signal launched on whole resource pool, and what therefore receiving terminal UE can judge and measure resource pool takies situation, such as, can measure all devices and find that service used resource accounts for the ratio of whole resource pool.In equipment, preset a threshold value, such as 80%, if the resource occupation ratio that receiving terminal UE records is more than or equal to this threshold value, then can be judged as that load is transshipped, otherwise think nonoverload.In another example, receiving device also can record the detectable signal number that in setting-up time section, success is decoded, and when the detectable signal number that total success of recording is decoded exceedes predetermined threshold value, such as 10, then can be judged as that load is transshipped.
In another kind of example, the indication information of device discovery resource overload also can comprise concrete overload value, such as: the device discovery service used resource that receiving terminal UE measures accounts for the concrete ratio value of whole resource pool.This ratio value is reported eNB.Or the detectable signal number of decode total success of concrete receiving equipment record and the difference of predetermined threshold value report eNB.
Wherein, network side is supplied to all devices and finds the resource that user shares, the selection that equipment emission detection signal can be random from this shared resource.Resource pool information can inform all devices by network side eNB by system information (SIB, SystemInformationBlock) and find user.
Step 102: network side eNB starting device finds premature beats strategy.
In the present embodiment, device discovery premature beats strategy can comprise:
Again device discovery user resource allocation pond is given;
Reduce device discovery number of users;
Reduce device discovery service number.
Wherein, network side is, when network side judges have more resource (namely having the idling-resource larger than existing resource pond) to can be used for device discovery, can find that user adopts new resource pool by announcement apparatus again to device discovery user resource allocation pond.
Network side has judged whether that more resource is for device discovery, can comprise the slack resources orthogonal with phone user, but also can comprise the resource shared with phone user and can be used as device discovery.
Particularly, in an example, network side receives the indication information of device discovery resource overload, and after judging to have unnecessary resource (resource pool that the resource pool just used than device discovery user is larger) to can be used for device discovery, directly this new resources pond is informed to device discovery user.In another embodiment, the concrete overload value size that network side can report according to user redistributes corresponding resource pool.If overload value is larger, then distribute larger resource pool, if overload value is smaller, then can distribute slightly little resource pool.
Reduce device discovery number of users to refer to, according to the priority of user, limit or forbid User Priority user's emission detection signal more rearward.The user of concrete minimizing how many device discoveries can determine according to the overload value reported.During concrete operations, can sort to User Priority, limit or forbid setting in User Priority sequence user's emission detection signal of sorting position, and the sorting position of setting can be one or several minimum position of sorting.
Reduce device discovery service number to refer to, according to the priority of device discovery service, limit or forbid service priority device discovery service emission detection signal more rearward.Concrete minimizing how many device discovery service numbers can be determined according to the overload value reported.During concrete operations, can sort to device discovery service priority, limit or forbid setting in service priority sequence the device discovery service emission detection signal of sorting position, the sorting position of setting can be one or several minimum position of sorting.
The above-mentioned three kinds of strategies mentioned can be used alone, and also can coordinate and use together.
It should be noted that, device discovery user involved in the present embodiment refers to the user related in the device discovery procedure of D2D, also can be described as D2D user.Device discovery service refers to the device discovery procedure of D2D.
The implementation procedure of said method is described from device discovery user side below in conjunction with Fig. 2, and this process comprises following operation:
Step 201: receiving equipment UE measures and judgment device finds load overload situations;
Particularly, on the resource pool that receiving equipment UE distributes at network side, receiving equipment finds detectable signal, and measures resource shared by detectable signal that all successes receive and account for the ratio of whole resource pool, carries out the judgement of load overload situations accordingly.
Or receiving equipment UE records the detectable signal number of successfully decoding, if the sum of the detectable signal of the successful decoding of record exceedes predetermined threshold value, then determine device discovery resource overload, do not exceed predetermined threshold value and then determine nonoverload.
Step 202: when determining device discovery resource overload, reports load overload indication information to eNB;
Particularly, can be that trigger-type reports also can be that periodic reports.
Step 203: coordinate and perform network side eNB premature beats strategy;
Particularly, device discovery user performs the combination of which kind of premature beats strategy or several premature beats strategy, can be specified by network side eNB by signaling.
Last composition graphs 3 illustrates the preferred version realizing said method, comprises following operation:
Step 301:eNB receives the indication information of the device discovery resource overload that device discovery user sends;
Step 302:eNB has judged whether that more resource is for device discovery, if judged result is yes, then enters step 303, otherwise jumps to step 305;
Step 303:eNB is that UE redistributes device discovery resource, has made more resource can be used as device discovery;
Particularly, in an example, this new resources pond is directly informed to device discovery user after judging to have unnecessary resource (resource pool that the resource pool just used than device discovery user is larger) to can be used for device discovery by network side.
In another embodiment, the concrete overload value size that network side can report according to user redistributes corresponding resource pool.If overload value is larger, then distribute larger resource pool, if overload value is smaller, then can distribute slightly little resource pool.
Step 304:UE carries out device discovery procedure according on eNB deallocated resources, process ends;
Step 305: by the priority restrictions device discovery number of users of user, not restrained user continues device discovery procedure, process ends;
Particularly, reduce device discovery number of users, according to the priority of user, limit or forbid User Priority user's emission detection signal more rearward.In another example, also can reduce device discovery service number, according to the priority of device discovery service, limit or forbid service priority device discovery service emission detection signal more rearward.
